Your height is controlled by two things: genes and environment.
let's look at genes first. genes are more important. if everyone in your family is tall, chances are, your genes will code for TALL. if you come from a family of Lilliputians (look it up if you never read 'Gulliver's Travels'), chances are, you got the short genes and you're just gonna be short.
Okay, suppose you have tall genes. Think about environment. If you have good environmental conditions (lots of food, plenty of sunshine and exercise, nurturing family), you stand the best chance of expressing your tall genes. You will be tall. But on the other hand, if you are malnourished, diseased, beaten by your parents regularly, live in a dark, damp room, and so forth, chnaces are, your body is not going to be able to build much with what little it's given. So despite the tall genes, you'll wind up short (and probably withered with lots of problems).
Sleep is an environmental factor. Sleep conserves our energy. It gives us time to heal and metabolize. People need more sleep during the phases of their lives when they grow the most (infancy and adolescence). If you deprive yourself of sleep, you give your body less time to build or replenish. Without that downtime for maintenance, your body will not reach its maximum or optimal growth, regardless of your genetics.
countrygirl, it just sounds like you got short genes. ain't nothing wrong with that. i'm not tall either, but that's fine by me.
